Improvement in ventilating railroad-cars



UNTTn STATES Trice.

ATENT d T. S. LAMBERT, OF PEEKSKILL, NEW YORK.

Speclication forming;` part of Letters Patent No. 410,@43, dated December 8, 1863; antedatcd December 4, 1863.

vact description thereof, reference being had to the accompanying drawing and the tigures marked thereon.

The nature of my invention consists in causing air to pass over ice into a car, by which means the dust of the air is deposited upon or adheres to the surface ot' the ice, the

air is cooled, and its condition made positively elect-ric, it' it be not so already, and to continue in that condition it' it is, and' to give it, perchance, or its moisture, a northern polarity. For this purpose let a closet be constructed with an opening. O, above upon one side and an opening, E, upon the opposite side below. Let it contain the shelves D D D, reaching nearly across, and on them let I, ice, be placed. B is merely a door.

lt is evident that the circulation of the air in the direction ot' the arrows will immediately take place, and if the opening,` C be connected with the front part of the car or with a recevingcap, and the ear is closed, except at proper exitplaces, as soon as the car is in motion it will be filled with deliciously, cool-bracing air, free from dust, and if it is too cool it can be warmed, and it not made too hot will not lose the electric condition it has gained when passing,` over the ice. A part of the A tube or duct may also be connected with the orifice E, so as to carry the cool air up toward the top of the car or elsewhere, as is desirable. But an opening,` at E directly1 into the car should be allowable, in order that when the car is standing` still the more perfect ventilation ot' the car may be produced. A similar structure will serve in a dwelling-house, hospitals, hotels, offices, or other like rooms, the air being' allowed to ilow in over the surface otiee. It is also to be observed that such air, being` reduced in temperature, will be to a corresponding degree dried. Other devices for exposing the air entering,` the car or a room to the action ot' the ice may be adopted. A case of drawers instead of a closet would do equallyT as well. A boX beneath the car could be easily adapted to the intention of passing the. air over the surface of ice. [n all these cases the ice should be laid upon bars, or holes should be made in the shelves to prevent the ice from lying in water, and the drip from one shelf to another should be so arranged that it w ll not run over the ice below.

What claim as my invention, and. desire to secure by Letters Patent, is

l. The application of ice to assist in the ventilation of railroad-cars, and for other purposes, substantially as set forth.

2. The construction ot' a closet with shelves or drawers for ventilation, by means of passing air over the surface ot' ice, substantially as set forth.

T. S. LAMBERT.
